Serial No. 458,173."

My invention relates to improvements in coal-handling machinery, more particularly in a combined picking table and refuse conveyer, and it consists in the combinations,

constructions, and arrangements herein described and claimed.

An object of my invention is to provide a device for facilitating the removal of refuse from coal so as to leave the latter in a clean 1 and salable condition.

p A further object is to provide means whereby the refuse may be removed and immediately conveyed to any suitable location, such as a dumping ground, without requiring any additional effort on the part of the worker.

VA further object is to provide a combined picking and refuse conveyer of the endless type in which means is provided for preventing the clogging of the conveyer. This means consists in a novel arrangement ofoverlapping plates which are so curved as to easily pass around sprockets at the ends of. the device, the plates forming a continuous bearing surface at all times as .distinguishedifrom other conveyers in which the plates are opened up or separated as they pass around the sprockets. r p

A further object is to provide a device of the type described in whichithe lower or re- 39 turn portion is utilized for conveying the re.

fuse, and in which the refuse is ,automati'cah ly delivered to chutes, thus obviating any further labor, on the part of the worker than the usual depositing of the refuse, which of course 1 is necessary in all devices of the type.

Other objects and advantages will appear in the following specification, andthenovel features of the invention will be particularly pointed'outin the appended claims.

-My invention is illustrated in'the accompanyingdrawings, forming part of thisapplication, in which Figure 1 Figure 2 1s a plan vlew,

Figure 3.is' an enlarged sectlon along the is a side elevation of the device, -15 the supporting floor being shown in section,

'Figure 5 is an enlarged section alongthe line 5 ,5 of Figure 2 i In carrying out my inventionIiprovide a frame consisting of uprights 1 which are. preferably angle ironsand to which are fastened cross beams2, as shown in Figure 3.1 Secured 'tothe upper inner sides of the members 1 are angle irons 3, while similar angle irons-:4: are secured to the members 1 near the ,bottoms thereof. InFigure 8 I have shown an upright with the upper and lower angle irons on one side of the device, but itgwill be understood that the opposite side is provided witli 'similar uprights and angle irons.

On each side of the'device, and spaced i111 wardly from the uprights '1, are supporting bars 5, see Figure 3, which are secured'to the cross members 2. v To these bars5: are secured plates 24; which e xtend upwa'rdly beyond the cross beams 2. Angle irons 6 are secured to the upper ends of the plates 24 and rest onthe cross beams 2; Similar angle irons 7 are securedto the lower ends of the plates 24, and these angle irons form runways aswill be described later. v

7 The bearing surface of the conveyer con sists of a series of plates '8 of the shape best shown in Figure 4.; These plates are of a general rectangular shape and are elongated as shown inFigure 2,.the long dimension; of the plates extending transversely of the longitudinal dimension of the'cOnVeyer as a whole. One'edge of the" plate is curved as shownat 8a in Figure .4, and at the opposite edge is welded or otherwise secureda curved portion 8?). curved concentrically about the central axial line of rollers 9. At the ends of the'plates,

The vportions 8a and' 8b are' thatfis to say atthe sides of the conveyer,

the plates have strips 80 for preventingthe material c'arried thereby from fallingoif.

, The rollers 9 aresecured to the body portion of the plates bymeans of angular shaped I brackets 10,and the axles of adjacent pairs ofrollers are connected means of links 11 and 110 As will be seen from the. drawings, these links are arranged in pairs, the links 11 being on-theoutside'of the links 11a. 7 At one end ofthe device is the driving mechanism. This consists, in the present inposite end or; the 'oonveyer. "T QThe teeth of.

' From theforegoing descript on of "the various partssof'the device,;the' operation thereof maybe readilyuhderstoodj The workers, iwhoi-clean thecoal of refuse,: stand on each j s'ide of the c'onveyer .between' the chutes 23.

Onegdilficu'ltywithan endless beltahas been to provide plates which'would supportthe *load and 'yett it would pass'around sprockets] "without being clogged. up" due: to the open- La ing up-"of thejspace between theplates. In

This is :due' to the construction 'te'i'showniinEigure" 4;,th ere being a relative 1-n1ovement"ibetween the parts SbJIand 8a ":around tha axes'of' the; ro'llers'as a centert" Thaportion ea however is always in jcontact thus interfere'with the proper working of the mechanism.

Use of this device obviates the necessity of long inclined chutes for the refuse, since the lower part of the endless belt is made use of for conveying the refuse to a point where it is desired to dumpit.
